GAS ANALYSIS DEVICE, MERCURY REMOVAL SYSTEM, GAS ANALYSIS METHOD, AND REMOVAL METHOD FOR MERCURY IN FLUE GAS

摘要

A gas analysis device includes a flue-gas extraction pipefor extracting flue gas from a flue gas duct to which flue gasincluding both of NH4Cl and SO3 is fed, a collector that is providedin the flue-gas extraction pipe for removing soot dust contained inthe extracted flue gas, a roll filter that is provided in the flue-gasextraction pipe, for depositing both of NH4Cl and SO3 containedin the flue gas, and a measurement device for measuring both ofNH4Cl and SO3 contained in the flue gas by irradiating a sampleincluding both of NH4Cl and SO3 deposited by the roll filter withX-rays and detecting fluorescent X-rays generated from the sample.
